UNITED STATES JOSEPH F. SARGENT, OF BOSTON, MASSACHUSETTS.

`IMPROVEMED NAILING OR PEGGING MACHINE.

Specification forming part of Letters Patent No. 77,104, dated April 2l, 1868.

To all whom it may concern:

Beit known that I, JOSEPH F. SARGENT, of Boston, in the county of Suffolk aiid State of Massachusetts, have invented certain Improvements in Nailing or Peg'ging Machines and I do hereby declare that the following, tak'en in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

Of the drawings, which represent a machine and parts and modifications thereo'fembodyin g my invention, Figure lis a side elevation, Fig. 2 a front elevation, and Fig. 3 a rear elevation, of what is known technically as the head of a machine.

In this connection it may be remarked that the head may be mounted on axed frame, in which case the feed-works will operate on a boot or shoe sole to feed the work with reference to the head, or the head may be used as a hand-machinethat is, the boot or shoe being held on a stationary holder, the head is steadied by the hand of the operator, who,

withthe other hand, turns the crank to cause the mechanism to operate, and then the whole head will be fed along or around the sole, the head being the moving` part, and the sole fixed but, where the head is fixed the shaft to which the crank is shown as connected is rotated by any convenient means.

Fig. 4 is a top plan of the head, and Fig. 5 is a reverse or underneath plan. Fig. 6 is a front elevation of the parts in the immediat-e vicinityof the awl and driver, the gage which determines the distance of the nails or pegs from the edge of the sole being removed. Fig. 7 is an end elevation of 'said parts. In both of said Figs. 6 and 7 the awl is represented as in the stock of the sole, while in Figs. 2 and 3 the awl is shown as withdrawn. Fig. Sis a plan and horizontal section, showing the cutter and carrier, which operates to cut, from a continuous wire like piece, short sections, which are then carried under the path of action of the driver. In said view the section is taken in the plane of the line z e. (Seen in Figs. l, 2, and 3.) Fig. 9 shows the cutter and carrier in plan, its position in this figure being that which it has after a section of Wire has been out off and-conveyed under the driver, when said cutter and carrier forms onehalf of the upper part of the nail-tube in which the driverl Works. In Fig. 8` the carrier is shown as in position to cut anail or peg from the length of material supplied for the pui'- pose. Fig. l0 shows, both in elevation and in plan, the ratchet-wheel, pawl-lever, and ratchet-shield, by which the wheels which feed the long wire to the cutter are operated so as to give nails ofA any desired length. Fig. l1 shows, both in elevation and in plan, the the wheels which operate on the wire to feed it down to the cutter.

On the main shaft c, to which power may be applied by'hand or otherwise to rotate it,

is a disk or plate, b, the periphery of which acts as a cam to force down the feed-.foot c against the action of spring d, to transfer contact of the sole-face from the end of the nailtube e. On the inner side of said plate b is a pin or roll, f, which operates on a projection on the driver-bar g to lift-it against the action of the spring h. On the other end of the shaft a is a cam, t', which operates on a pin or roll in the awl-barj to lift it against the action ot' spring k. On the outside of cam z' is fixedl a crank-piii, which, through link l, works the lever m, which carries the pawl n, which works the wire feed ratchet-wheel o. On the inside of cam t is fixed a wiper-pin, which operates against a lever, p, to cause said lever to move .theswing-piece q, which is pivoted at r, there being a spring which acts in opposition to the Wiper-pin. The feed-foot bai' being fitted in said piece q, it will be obvious how the feeding movement of the machine, or of the the stock, with reference to the machine, is produced. is formed in one end of a bent or angled lever, s, which is moved through the link t, which, taking hold of the other end ot' said lever, connects it with the swing-piece q, so that, as the feed-movementtakes place, by which the distance apart of Vthe nails is determined, the wire is cut otf from thecoil, and is conveyed under the driver, by which it is driven into the sole. On the shaft to which the ratchet-wheel o is fixed is a spur-gear, which meshes into an equal spur-gear on a parallel shaft, the twoI shafts having, on their other ends, Wheels which have serrated grooves around their peripheries. These wheels, which are marked The cutter and carrier of the wire the wire to the action of' the cutter various` lengths, to obtain desirable lengths of nails, and as the stroke of the pawl is constant and `wouldgive a constant feed, the following means areused for making more or less of' `the stroke of the pawl effective in turning the ratchet-wheel: Pivoted on theratchetwheelt, shaft is a shell, n, which covers part ofthe periphery of i theratchetwheel. Part of' this shell is cut away so astoexpose aportion of l theperiphery of the ratchet-wheel o. Now, by adjustment of this shell,` more or less otiit maybe present under ther pawl, so.that the:

pawl, in moving, travels overmore or less of' the shell, and thus acts upon anumber ot' teeth of the ratchet proportioned to theadjustment of' the shell. `The shell is turned on its-centerjby an arm, w, which isprovided with a spring-catch, which can meshinto any one of' the not-ches madeina notched rack, ai. Theoperation of `the mechanism described is as follows: iThecrank being lintheposition` shown in Fig. 2, the lower end of the peg-tube Aisili-contact with the sole, and so also is the lower end of the driver. Now, by turning the crank in the direction indicated bythe arrow, the feedfoot, being f'reefrom contact with the sole,.1noves Aaway from the tnbe,and then is `forced down uponfthesole, transferring con-vr tact from the tube end to the feed-foot, and then the awl descendsunder `the influence i of its spring and `make a hole in the sole, from which the` awl immediately withdraws, and the driver moves upto be in readiness to make Vits downward stroke, to drive a nail into the hole made bythe awl, and the feed-foot causes movement which brings -the lawt-hole under the tube,` through which the driver descends. While the awl moves upward the wheels u areoperated to draw down aportion of the wire from the reel on which it is wound, and,

as the feed-foot moves toward the nailtube e,-

rtheicutter and 'carrier operate `to cut ofi' a nail from the wire, and. toconvey it from the line in; which it is ,drawn oli1 `from itsreel` `to the line in which the driver operates. The driverhaving descended and driven the nail in the tube out therefrom into thesole, the feed-foot rises and transfers contact with the sole from itself `to the end ot the nail-tube, preparatoryto drawing away'rom the nailtube. i t i The' nail-tube is made of' an upper and a lowerpart. The lower part is a tube, drilled in solid material, and `its length is at least and carrier to the position seen in Fig. 9 severs a piece from the long length of' wire. The cut thus made is substantially square, and, as it may be of' some utility to point the enteringends of the wire pieces, `some devices for that purpose are shown in the drawings.

Figli). shows, in plan and in elevation, a device which cuts out a kind oi' triangular section from thewire, so asto Ieavethe end of' the wire, which istoreceive the action `of the driver, square, and theend ofthe wire above, which will be theentering end of' the next nail, beveledfrom one side to the other.

Inthiscase there is fittedabove the carrier, and in the material of the solid tube above, a slide, `moving inthe joiutof saidpieces, said slide acting not only to cut oft the nails from the wire, butto point thenails as well. The slide thus acting as acutter, the piece s has only left the functions of acarrier. The slide referred to is marked y in Fig.. l2. and cuts with the end that crosses the tube through which the wire isdeliveredto the carrier, the

edge of the slidebeing beveled, so as to make v the angle or bevel ot the nail-points i more `or less acute, as maybe desired.

. In Fig. 13 are shown,.in plan, elevation, and in 4detached views, a slide, and its arrangement, by whichthe topsof the nails are cut off square, and the points are made withtwo bevels, two triangular chips being removed from 'the wire in the cutting-oft' and pointingoperation, with the slide shown, which is marked y. i i Various kinds of material may beused'in this machine; for example, comn1on wire, of' iron, brass, or copper, or flattened and twisted wire," such as isshown `in theidetail` views, marked AB, or thread-peg material, such as is shown in the views C `D, the onlyipeculiarities needed in thenail or `peg forming material, for .use with theimechanism described,

being sufficient rigidity to enable it to be, r

driven, while supported in a tube, under .the action of a drivel-,and a long wire-like f'orm, so that the nails or pegs are formed from and in the direction of the length of' the material.

l. A pegging or nailin g machine, constructed substantially as described, so as to operate to automatically cut,\at one location, short pieces from along or wire-like formation of material, and to convey them, when so cut, to another location, where they receive the action of the driver. I

2. Also, the tube, or apart thereof, through wma. 1 s

which the nails or pegs are to be forced into or t toward the material to be united, made in two parts, capable of bein g closed and separated on a longitudinal plane passing through the tube, 4 substantially as and for the purpose specified.

3. Also, the tube through which the nails or pegs are forced by the driver, made in two or more parts, of which one division is made substantially at right angles to the axis ot' the tube, so as to enable onepart of the divided. tube to bc moved with respect, to the other part or parts, substantially as and for the purpose described.

4. Also, the combination of the tube or groove, through which the Wire is thrust to be subjected to the action of a cutter, with a cutter for severing a nail or peg from the Wire or wire-like material. 1

5. Also, the combination of yintermittentlyoperating feed rolls or wheels, for feeding material of a Wire-like form, with cutters for cutting oft' the material so fed, to form nails or pegs, substantiallyT as described.

6. Also, in combination with feedivheels,

for supplying lengths of wire-like material to Y the cutters, the ratchet Wheel and pawl, and the adjustable shell or shield fv.

7. And I claim a pegging or nailing machine, constructed substantially as described, so as to operate in producing a correct register ofthe aWl-holc beneath thev driver, by irst transferring the contact ot' the sole from the nail-tube to the feed-foot, then causing the awl to enter and withdraw from the sole, then giving the feeding movement, to bring the awl and driver-holes in register, and keeping the contact of the feed-foot with the stock till the driver has made its driving-stroke, after which, by vertical movement of the feedfoot, contact of the sole is transferred to the driver-tube.
